此版本的 CLI 仅与 Angular 版本 ^13.0.0 兼容，但找到了 Angular 版本 12.2.13

Question

我的Ionic项目一个月前运行良好。今天，当我尝试ionic serve或 时ionic build，出现以下错误：

哪个 CLI 版本与 Angular 版本 12.2.13 兼容？如果你真的想知道我为什么问这个问题，你可以进一步准备。

所以我按照 Angular 官方网站上的建议升级到 Angular 13，我使用了以下命令：npm @angular/cli@13 update @angular/core@13 @angular/cli@13。

该路线要求我将 Node.js 升级到版本 16（最新、当前）。将 Node.js 升级到 v16 后，我重新尝试升级到 Angular 13，在此过程中，由于不支持的依赖项等原因，安装失败/停止。

我用谷歌搜索了大多数解决方案，进行了尝试，最后得到了一个项目，其中我的所有插件都找不到，等等。因此，我通过将 Node.js v16 卸载到 v12 来反转上述过程，删除 npm、node_modules文件夹，现在我又回到了图中出现以下错误的位置。

这是我的开发环境ionic info：

Answer 1

npm i @angular-devkit/build-angular@12.2.13 --force
npm i @angular/cli@12

Answer 2

我有同样的错误，但我使用的是 V 11.2.14。

简单的解决方案是转到package.json文件并更改

"@angular-devkit/build-angular": "^13.0.2"

（它在依赖项内部）

到您的兼容版本。

所以当我把它改为

"@angular-devkit/build-angular": "~0.1102.3",

有效。

Answer 3

如果你使用@angular-builders/custom-webpack

无论谁遇到此问题，请更新到package.json@angular-builders/custom-webpack文件中的最新版本。

Answer 4

如果您想跨多个主要版本更新您的 Angular 版本- 如果您在使用“ng update”时收到以下错误 - “不支持一次更新‘@angular/cli’的多个主要版本。请单独迁移每个主要版本.在工作区目录中运行“ng update @angular/cli@12”以更新到“@angular/cli”的最新“12.x”版本。

您必须执行以下步骤才能逐步更新：

1. 跑步ng update
2. 您将获得要使用更新命令更新的项目列表
3. 运行每个命令来更新--allow-dirty --force

对于和例如：

要在此处更新 Angular cdk，请运行ng update @angular/cdk@12 --allow-dirty --force

4. 对列表中的所有项目执行与上面相同的操作
5. 使用给定的命令完成更新项目后，再次运行ng build并检查所有错误是否消失。
6. 如果您遇到更多有关更新的错误，请再次运行ng update并继续执行步骤 2 至 5，直到解决所有更新错误
